To compare surgical outcome in mesial temporal lobe epilepsy (MTLE) patients with unilateral hippocampal sclerosis (MTLE-HS) who had or did not have preoperative video-electroencephalographic monitoring (VEEG). ⋯ We performed the first prospective study in a tertiary epilepsy center comparing surgical outcomes in unilateral MTLE-HS patients investigated preoperatively with and without VEEG. Based on the surgical outcome, VEEG is not imperative in patients with unilateral MTLE-HS who have compatible semiology and clearly ipsilateralized IEDs evaluated by a multidisciplinary and experienced epilepsy group.

γ-Aminobutyric acid (GABA) is the major inhibitory neurotransmitter in adult central nervous system, and profound alterations of GABA receptor functions are linked to temporal lobe epilepsy (TLE). Here we describe the functional relationships between GABA receptors type B (GABAB R) and type A (GABAA R) in human temporal cortex and how TLE affects this aspect of GABAergic signaling. ⋯ Our results highlight the association of TLE with functional changes of GABAergic signaling that may be related to seizure propagation, and suggest that the selective activation of a definite subset of nonpresynaptic GABAB Rs may be therapeutically useful in TLE.
